t bicarbonate, with bicarbonate being more prevalent during high flow conditions. These ionic <br />conditions also influenced the conductivity and TDS as exhibited in the graphs in <br />' Appendix 1. <br />Analysis of trace metals indicates ]ow concentrations. Aluminum and iron were detected <br />' in all samplings, higher values being reported during high flow events (Appendix 1). <br />Manganese and zinc were also sampled and found in only trace amounts. <br />' Mining and reclamation operations at the Chimney Rock Mine appear to have little or <br />no effect on the quantity or quality of area surface waters. This may be due to the mines <br />inactive status during 1985 through 1989. Baclc511 and grading activities occurred in the <br />' Revision 1 Pit and Surface facilities during 1990 and 1991; however, sediment control ponds <br />established on the disturbed areas eliminated runoff of surface waters from the mine site. <br />All IVPDES forms were Sled with the Department of Health during quarterly reporting <br />periods. CMLRD also received copies of these reports. During 1991, no discharges were <br />reported from any of the ponds. <br /> <br /> <br /> <br />
